Having bought a new trailer and a raft, I'm concerned about my stuff getting stolen. I live in Bozeman,MT and see everyone parking their raft/trailers on the side of the road. To me, it seem like it would be fairly easy to just hitch up and drive away. Does anyone use a hitch lock? My other concern is doing day/multi day floats and using a shuttle. Most of these places are fairly remote or out of the view from a main road. Is there any sufficient way to secure the trailer to my vehicle?
